How to keep your glasses from fogging up while wearing a mask

As we all know the Governor  has issued an order for everyone to wear a mask when social distancing is not possible and we must wear masks in grocery stores etc. to protect ourselves and those around us.    I wear glasses and found that they fog up when wearing a mask.   I picked up this tip from facebook.  If you tie a knot in the part of the mask (as shown) that goes over your ear, the mask is then tighter and  air will not escape from the top of the mask and fog up your glasses

Thank you Mickey Vertino and the University Heights Collaborative and ABC Hardware for donations and distributions of masks to our community.
